FLYING-MAGHINE.

To all whom it may concern: 7

Be it known that 11, CHARLES ,M. HUN

sienna, a citizen of theUnited States, re-

siding at Dayton, in the county of Mont .gomery and State of Ohio, have'inv'ented' certain new and useful improvements in lowin Flying-Machines; and I do declare the folto be a full, clear and exact (lesc.-ipt1on of the invention, such as will on able others skilled in the art to which it 'appertains to make'and use the same, referencebeing had to the accompanying drawings, and to the letters and figures of reference marked thereon, which for-ma part f this specification.

This invention relates to'flying machine s,

and particularly to'fiy'ing machines of the I combined aeroplane-helicopter type, the object of the invention being to'prov'ide a flyin -machine of this character which 1s fsiinp e of construction, reliable and efiicient of Working in action, and embodies a minimum number parts, as will hereinafter more fully appear. I

A further object of the invention is to provide a flying machine having a supporting surface formed of sustaining planes which may be readily and conveniently furled or reefed when it is desired to reduce" resistance to ascension or descenslon, and

which may be 'unfurled' or unreefed for use when it is desired to employ an aerofoil or sustaining surface. v

With these and other objects in view,jthe invention consists of the features of construction, combination and arrangementjof parts hereinafter iully described. and claimed reference being had to the accompanying .clrawings in which Figure 1 is a top plan view of the machine with the.

wings or sustaining lanes spread; Fig. 2 is a side elevation of t e mahhine withvparts broken away to facilitate clearness; F i 3 is a vertical longitudinal section throng the machine, on the line'3-3 of Fig. 2;

Fig. i is a vertical transverse section on the line H of Fig. 2; Fig.5 is a yertical'transverse section on the line 5-5 of Fig. 2.

In carrying my invention into practice, I provide a main frame 1, WhIClYlSSllOWll in thepresent instance as'subst-antially of oblong rectangular form and provided vith tapered or V-shaped bow and stern por ions "2 and 3. The machine is shown as provided with lugs t for supporting the same on wheels 4 When at rest upon the ground sur Application filed July 12,

gear for land o'r marine use. Arranged at the frontan'd suitable type of launching and. alighting rear of the face, but maybe provided with any other machine are verticalgshafts fil and 6 which] extend to, a desired-"elevation f'above the Q A framework and carry. fore-and-aft lifting.

The shafts 5 and 6 arejou rnaled in suitable bearings and shaft 115 is provided.-

o the seat 21 and operated upon the outer-end of a horizontal longi f tudinally extending shaftdl? Whichcarries a pinion 18 meshing with a gear on a shaft 40. v The shaft 40 is mounted V suit able'bearings and is connected through a clutch 20 to a sprocket 42vwhich in turn is or planes, whichare preferably in the form m of right angle triangles, have their basesforwardly disposed, .their straight sides arranged in proximity and in parallel relation to the sidesof-the main frame. and their inclined sides outwardly disposed, the said base portions of the wings being provided with horns or pockets 25 which slidably receive and engage the wing spars 23', the reduced or apex portions of the wings being secured to the main frame, as indicated at 26. These wings 24 when unfurled or spread [provide a supporting or aerofoil surface to -'furnish withnthe frame and tractor a motor driven gliding structure for straightway travel. in the air, the wings also serving, when des1red, as brak1ng surfaces to reduce 1' the s eed of descent in downward travel. In

starting the flight, the machineis driven up wardly by means of its lifting and sustaining propellers, which are operated at high speed, during which time the wings are furled or rcefed, but as soon as the desired altitude is reached the speed of the lifting propellers may be reduced and the driving propeller thrown therewith into action, the driving propeller being driven at its normal I traction speed to adapt the lifting propellers to act in conjunction with the wings as sustaining elements, the wings being, as soon as posite directions on drums upon a crank shaft 31 which is operated from'the crank portion 32 thereof. The sets of cables of the two wings are connected to different drums for conjoint operation, whereby when the xcontrol crank 32 is turned in one direction Both wings will be spread While when said control crank is turned in the opposite direction both wings will be furled. In the qfurling and unfurling motions of the wings,

the pocket portions 25 thereof slide inward and outward on the wing spars 23, as will be readily understood.

It will be seen from the foregoing description that a machine is provided which partakes of the properties and advantages of both the aeroplane and the helicopter, and which'in the event of damage to its wings or tractor propeller may still be sustained in the air and brought to a safe landing. The

machine is also capable of being driven ahead with considerable speed while being supported by the-lifting propellers, and may be caused to ascend or descend directly-at a greater or less speed without tilting the machine to an upwardly or downwardly inclined angle to its normal flying position. These and other advantages will be apparent. A vertical rudder 35 is arranged at. the rear of the main frame and connected by cables 36 with a control wheel 37 whereby the machine may be steered laterally in an obvious manner by turning said wheel.

Having described my invention, I claim.

1. In a flying machine, the combination of.

front and rear lifting and sustaining propellers mounted on vertical shafts, forward driving propeller mounted horizontally, a motor, a transmission shaft geared to the shaft of the rear lifting and sustaining propeller, transmission shaft geared to the forward driving propeller, a chain drive connecting the motor shaft with the transmission shaft of the rear lifting and sustaining propeller, a chain drive connecting the shaft of the rear lifting and sustaining propeller with the shaft of the front lifting and sustaining propeller, and a chain drive connecting themotor shaft with the shaft of the fiorward driving propeller, substantially as c escribed,

2. In aflying machine, a main frame, forward and rearward lifting and sustaining propellers, a forward driving propeller, wing spars extending laterally from the forward" portion of the frame, triangular sustaining wings mounted at oppositesides of the frame and eiitending from the forward to the rearward lifting and sustaining propellers, the forward edges of said triangular sustaining wings being provided with pockets which receive the wing spars and are thereby supported in a position to be extended or reefed, and cables connected with said wings for operating the same, substantially as specified.

In testimony whereof I my signature in presence of two witnesses.
